Thanks Tom for posting this. I had 'discomfort in my shoulders' earlier this year - I couldnt localise it so I didnt describe it as 'pain' and it was higher than I call chest. I'm 42 and had no risk factors for a heart attack. I called NHS direct looking for advice on painkillers. They called an ambulance. Paramedics said it probably wasnt cardiac but took me in to get it checked out. A&E doc said it probably wasnt cardiac but did a blood test to check. I had had an infarction - it turned out to be caused by an autoimmune vasculitis, rather than atherosclerosis. I am so grateful for the professionalism of all those in the health service, who took it seriously even though they thought it wasnt likely to be serious, and ignored my continued apologies for wasting their time with what I thought was bad RSI. I wondered if the paramedics went away (not knowing they outcome) thinking it was a 'waste of time' job, but I hope they shared your attitude.
